When it comes to Antivirus programs – There can be only one
Ever think that a computer has better protection if it has two antivirus programs running at the same time? Well, you might want to rethink because in this case, one is better than two.
One of the most common complaints often is that a user’s antivirus is not scanning anymore, even though it was just fine the day before. In these cases the problem is almost always the same thing: Two or more antiviruses installed on the same computer. No matter the operating system, the same principle applies as in “Highlander”: There can be only one.
What does it mean?
Whenever you are having two or more antiviruses running at the same time, you are creating the potential for big problems for your PC and in the long run yourself. Antivirus software is rather complex and has many components which may interfere with each other, as one antivirus may block one of the other AV’s components.
Depending on how their quarantine routine works, a file that has been quarantined by the first antivirus may be detected by the second one – even if it no longer poses a threat. Or one of the antiviruses may block the file while the other one is trying to move it into quarantine, resulting in a variety of errors.
What’s worse is that they may even miss a threat: If one antivirus opens a file for scanning, the other may not be able to read it. So if the first one doesn’t detect it, the second one may not have a chance to do so either.
You also need to take into account that two antiviruses will need twice as many resources, meaning more RAM and processing power – especially when performing a scan or other security-related operations. In the end, your computer will be at least noticeably slower if not unstable.
When it comes to your antivirus, more can mean less. So whether you are in the Highlands or the Lowlands, please remember that your computer has no room for two swords. There can be only one.
